perf tools: Fix const char type propagation
The following perf build warnings/errors in function argument types: builtin-sched.c:1894: warning: passing argument 1 of 'sort_dimension__add' discards qualifiers from pointer target type util/trace-event-parse.c:685: warning: passing argument 2 of 'read_expected' discards qualifiers from pointer target type util/trace-event-parse.c:741: warning: passing argument 4 of 'test_type_token' discards qualifiers from pointer target type util/trace-event-parse.c:706: warning: passing argument 2 of 'read_expected_item' discards qualifiers from pointer target type ... trigger because older GCC is not able to prove that sort_dimension__add() does not change the string. Some goes for test_type_token(). Fix this by improving type consistency.
